.While I have in the above specification shown and described but a single embbdiment of my invention, itis to be understood that it is capable of modification. Changes,

therefore, in the construction and; arrangement of parts may made without departing from the spirit and scope o'l 'the invention as expressed in the appended claims.

I claim i 1. In a harrow unit, a frame, disk gangs thereon, draft members connected: to said frame, means cooperating with said draft members for automatically controlling the angle of the gangs, saidmeans' including a cross member connecting said draft new bers, a pendant linko'n the frame connected to the gangs, anda, rod hinged to said cross member and supported On said link below the frame for operatively connectingthe disk gangs and the cross member.

2. In a double disk harrow, front and rear sectiong connecting means between said sections permitting themto approach each other, the rear section having afrarne, disk gangs, hingedly mounted thereon, a rod suspended below the frame and having one end supported onfsaidfconnecting means, and means for connectlng, said 10Cl"aI1Cl; Sa1d d k senesw a thei i s tas ed er y s nse ma e traig e ed 0a beekn a do ble. di k arren. on an rear sections, connecting means between said e i ns p m tine" h e to, arr ae t ers he re e iea a ies r m i gangshinged1y mounted thereon, a rod suspended below the frame and movableiciith said comiectingmeans. andm'eans between a d; rod dl i l k. manner th ne m y b htened on a king an angled by a forward pull;

5. In a harrow, front and rear harrow units, disk gangs on said units, telescopic means for connecting said units, an equalizing bar carried by said telescopic'means, and a rod hinged on said equalizing bar and suspended below the frame and connecting said bar and the rear disk gangs including means for causing them totake and holld an angled position. 6. In a h-arrow, front and rear harrow units, disk gangs on said units, telescopic means for connecting said units, an ecplralizing bar carried by said telescoping means, a rod hinged on said equalizing-bar and suspended below the frame and connecting said bar and the rear disk gangs including means for causing them to take and hold an angled position, and means for releasing the gangs from said angled position when the barrow is. moving forward.

' 7. A disk harrow attachmentfor-imple.

In a double harrow, front and rear frames, disk gangs thereon,telescopic means for oining said frames'a pm connected to' the inner ends of saidrear gangs, a sliding link connected tosald telescopic means having ratchet teeth, and a stop notch so arranged that as the harrow is backed the pin. Will pass over the ratchet teeth' and engage the stop notch thereby causing the rear.

gangs to straighten, and whereby the pin Will engage one of the ratchet teeth when the harrow is next advanuced thereby angling the rear gangs.

13. In a double harrow, front and rear frames, disk gangs thereon, telescopic means for joining said frames, a pin connected to the inner ends of said rear gangs, a sliding link connected'to said telescopic means having ratchet teeth, a stop notch so arranged that as the harrow is backed the .pin will pass over the ratchet teeth andengage the stop notch thereby causing the rear gangs to straighten, and means for dlsengaging said pin and: sliding link.

14-. In a double harrow, front and rear frames, disk gangs thereon, telescopic means for joining said frames, a pin connected to the inner ends of said rear gangs, a sliding link connected to said telescopic means having ratchet teeth, a, stop notch so arranged that'as the ha'rrow is backed the pin will pass overthe ratchet teeth and engage the stop notch thereby causing the rear gangs to straighten, and whereby the pin will en gage one of the ratchet teeth when the harrow is next advanced thereby angling the rear gangs, and means for disengaglng sa d pin and sliding link.
